The best performing LCD and OLED displays are now delivering impressive sharpness, brightness, low reflectance, high color accuracy, accurate image contrast, and great viewing angles. The Color Shifts with Viewing Angle are also very small. Mobile payment is now a common theme amongst most smartphones.

Steve Jobs and Apple also made display-quality a central theme for their product marketing. It was a brilliant technical and marketing innovation, and the competition was left in the dust….

But then iPhone display innovation slowed almost to a crawl: In with the iPhone 5, the new display enhancements were increasing the Color Gamut up to percent sRGB and bumping up the display size from 3.

In the iPhone 5s display stayed the same mid-cycle refresh. This could be a touch of the Blackberry effect the display is already perfect, or perhaps a bit like the tale of an intermittently sprinting Hare losing to the steady progress of a Tortoise… more on this in the Conclusions.

While Apple display innovation slowed, many other manufacturers just steadily pushed ahead to take the lead. The new iPad mini Retina display, for example, came in a distant third place finish due to backpedaling its Color Gamut down to 63 percent from percent in earlier Apple products and in many competing products.

But there are now four years of catching up to do, and there are many more display issues in addition to screen size, which is the simplest one that has gotten the most attention.

In either case, it is significant that Apple wants everyone to know that display performance is important, and that they have been working to improve the displays on the new iPhones… And they did!

The likelihood of sapphire appearing on the iPhone 6 was close to zero because it will probably take at least another year for everything to come together. It is important to note that sapphire has some downsides over and above its much higher cost and manufacturing complexity.

The most important issue for display performance is that sapphire has almost double the screen Reflectance of glass due to principles of optics, so it will be harder to read sapphire screens in high ambient light.

That might be one reason why the recently announced Apple Watch Sport edition has a cover glass rather than sapphire like the other models — because it is much more likely to be used unshielded in high ambient light outdoors.

Another reason is that while sapphire is very hard it is also brittle and is likely more prone to impact breakage, which is more common in sports situations. So, if given the choice, I personally would choose a cover glass with its better screen visibility and breakage protection.

Others may find the scratch protection more important. To examine the performance of the iPhone 6 and 6 Plus displays we ran our in-depth series of Mobile Display Technology Shoot-Out Lab tests and measurements in order to determine how the latest LCD displays have improved.

We take display quality very seriously and provide in-depth objective analysis based on detailed laboratory tests and measurements and extensive viewing tests with both test patterns, test images and test photos.

In this Results section we provide Highlights of the comprehensive DisplayMate Lab tests and measurements and extensive visual comparisons using test photos, test images, and test patterns that are covered in the advanced sections.

You can also skip these Highlights and go directly to the iPhone Conclusions. That is the origin of the often misunderstood Pixels Per Inch ppi. The iPhone 6 has a x pixel display with ppi and the iPhone 6 Plus has a x pixel display with ppi.

While the display on the iPhone 6 has almost identical performance to the iPhone 6 Plus, it only has a 1. For one, it is particularly important to have as many pixels as possible when digitally rescaling images from their native resolution to the display that they are being viewed on.

Most images require rescaling and most rescaled images from either higher or lower resolutions with fine text and graphics look noticeably to considerably better in side-by-side comparisons on the iPhone 6 Plus with 2.

Twice as many pixels to work with makes a noticeable visual difference. In addition, even with content at their respective native display resolutions, fine text and graphics look better on the iPhone 6 Plus.

The display on the iPhone 6 is none-the-less still a Very Good display, and most buyers will be happy with its performance. For Smartphones they include a closer match to digital photo resolutions, the ability to display standard Full HD x images and videos at their native resolutions.

For the iPhone 6 Plus no rescaling is required for Full HD content, which always results in the best possible image and picture quality. So, when you are looking at an image with very finely detailed graphics and small text, most people with reasonably good vision will be able to make out and take advantage of the extra sharpness and image detail if they take the time to do so.

See our Innovative Displays and Display Technology article for more details. See this Figure for the measured Color Gamuts. In order to produce high Absolute Color Accuracy a display also needs an accurate pure logarithmic power-law Intensity Scale, and an accurate White Point.

The new iPhones both have very accurate Intensity Scales with a Gamma of 2. Both are Very Good, among the most accurate mobile displays we have ever measured, and are very likely considerably more accurate than your living room TV.

Mobile displays are often used under relatively bright ambient light, which washes out the image colors and contrast, reducing picture quality and making it harder to view or read the screen.

To be usable in high ambient light a display needs a dual combination of high screen Brightness and low screen Reflectance — the iPhone 6 and 6 Plus have both. The screen Reflectance for both new iPhones is 4.

Our Contrast Rating for High Ambient Light quantitatively measures screen visibility under bright Ambient Light — the higher the better. As a result of their high Brightness and low Reflectance, the iPhone 6 and 6 Plus have a Contrast Rating for High Ambient Light of, among the highest that we have ever measured and also the same as the much smaller iPhone 5.

This is unusual and is due to the detailed automated factory calibration performed on every individual display at the factory. Apple is one of the few remaining manufacturers to actually provide display specifications.

Note that the very high Dynamic Contrast Ratios claimed by some manufacturers are meaningless and pure nonsense. And for those of you thinking of Emailing that we got hand-picked units, these were purchased retail from Verizon Wireless.

See the Brightness and Contrast section for measurements and details. They are 10 percent more display power efficient than the Full HD LCD Smartphones that we tested, impart due to the different ppi, which is a factor.

Comparing them to latest OLEDs: LCDs are typically more power efficient for images with mostly white content like text screens, for example, while OLEDs are more power efficient for mixed image content because they are emissive displays so their power varies with the Average Picture Level average Brightness of the image content.

For LCDs the display power is independent of image content. See the Display Power section for measurements and details. While Smartphones are primarily single viewer devices, the variation in display performance with viewing angle is still very important because single viewers frequently hold the display at a variety of viewing angles.

The angle is often up to 30 degrees, more if it is resting on a table or desk. Particularly important and noticeable are the much higher Contrast Ratios and the lower Brightness Decrease with Viewing Angle.

The Color Shifts with Viewing Angle are also very small. See the Viewing Angles section for measurements and details. The iPhone 6 and 6 Plus provide very nice, pleasing and accurate colors, and picture quality.

The very challenging set of DisplayMate Test and Calibration Photos that we use to evaluate picture quality looked Beautiful, even to my experienced hyper-critical eyes. But this only holds for viewing in low Ambient Light.

The primary goal of this Display Technology Shoot-Out article series has always been to point out which manufactures and display technologies are leading and advancing the state-of-the-art of displays by performing comprehensive and objective Lab tests and measurements together with in-depth analysis.

We point out who is leading, who is behind, who is improving, and sometimes unfortunately who is back pedaling… all based solely on the extensive objective measurements that we also publish, so that everyone can judge the data for themselves as well… See the main Display Shoot-Out Comparison Table for all of the measurements and details.

The iPhone 4 not only revolutionized the displays on Smartphones but it also started a major unprecedented renaissance of new display technologies for Smartphones, Tablets, TVs, and entirely new classes of products like wearable displays.

That approach impressed consumers and moved the entire display industry. Then for reasons we can only guess, innovation on the iPhone displays slowed down almost to a crawl, while many other manufacturers just steadily pushed ahead — so there was a fair amount of catching up to do….

While screen size has gotten the most attention, there are many more important and challenging display technology issues that Apple needed to address and enhance… And they did! It delivers uniformly consistent all around Top Tier display performance.

Resolution x versus x, Pixels Per Inch ppi ppi versus ppi. The display on the iPhone 6 has almost identical performance to the iPhone 6 Plus — but it only has a 1. It is particularly important to have as many pixels as possible when digitally rescaling images from their native resolution to the display that they are being viewed on.

Most rescaled images look noticeably better on the iPhone 6 Plus with 2. In addition, even at the native display resolution, fine text and graphics look better on the iPhone 6 Plus if you look carefully and closely at the screen because you may want to or need to.

Maybe that was done for intentional product differentiation with the iPhone 6 Plus, or perhaps to improve their margins… With a x display the iPhone 6 would have taken the crown….

The technologies are significantly different and each one has its own inherent strengths. The iPhone 6 with a 4. The iPhone 6 Plus with a x display with ppi corresponds most closely with the Galaxy Note 4 5.

You can compare all four displays in detail by using a tabbed web browser with our comprehensive Lab measurements and analysis for each of the displays. Click on each Link below. Another way to compare them is by the relative strengths of each technology, which are listed below.

Then refer to the individual Lab Measurements Links above in order to get the values for the categories of interest. Both are impressive and excellent displays with great state-of-the-art display technology.

We recently gave the Samsung Galaxy Note 4 our overall Best Smartphone Display award, and for the time being that continues for all of the reasons originally mentioned there.

As we discuss next, dynamic Color Management is something that every display will need to provide in the future. With display technology advancing rapidly on many different fronts, things can change again in the next generation of displays — so best wishes to all of the manufacturers and technologies in innovating and developing the next generation of even higher-performance displays!

The best performing LCD and OLED displays are now delivering impressive sharpness, brightness, low reflectance, high color accuracy, accurate image contrast, and great viewing angles. So what comes next?

Essentially all published display specifications and factory calibrations are based on performance in absolute darkness 0 lux, but mobile displays and even TVs are seldom viewed in the dark.

Even low levels of ambient light significantly affect the image and picture quality. At lux, which corresponds to typical indoor office lighting, the on-screen colors are washed out by the reflected ambient light, typically reducing the on-screen Color Gamut from percent down to 80 percent, plus the image contrast is also significantly affected.

And it gets worse as the ambient light levels increase. So here is what needs to come next…. The most important improvements for both LCD and LCD mobile displays will come from improving their image and picture quality and screen readability in ambient light, which washes out the screen images, resulting in reduced image contrast, color saturation, and color accuracy.

The displays, technologies, and manufacturers that succeed in implementing this new high ambient light performance strategy will take the lead in the next generations of mobile displays… Follow DisplayMate on Twitter to learn about these developments and our upcoming display technology coverage.

Mobile payment is now a common theme amongst most smartphones. Today, smartphones largely fulfill their users' needs for a telephone, digital camera and video camera, GPS navigation, a media player, clock, news, calculator, web browser, handheld video game player, flashlight, compass, an address book, note-taking, digital messaging, an event calendar, etc.

Typical smartphones will include one or more of the following sensors: Most smartphones produced from onward have high-speed mobile broadband 4G LTE capability and touchscreen starting to grow in use more.

Smartphones started to expand in the third quarter of In the third quarter of, one billion smartphones were in use worldwide. The first commercially available device that could be properly referred to as a "smartphone" began as a prototype called "Angler" developed by Frank Canova in while at IBM and demonstrated in November of that year at the COMDEX computer industry trade show.

In addition to placing and receiving cellular calls, the touch screen-equipped Simon could send and receive faxes and emails. It included an address book, calendar, appointment scheduler, calculator, world time clock and notepad, as well as other visionary mobile applications such as maps, stock reports and news.

The first integration of data signals with telephony was conceptualized by Nikola Tesla in and pioneered by Theodore Paraskevakos beginning in with his work on transmission of electronic data through telephone lines.

In, while he was working with Boeing in Huntsville, Alabama, Paraskevakos demonstrated a transmitter and receiver that provided additional ways to communicate with remote equipment. This formed the original basis for what is now known as caller ID.

The original and historic working models are still in the possession of Paraskevakos. These operating systems would later evolve into early mobile operating systems. Most of the "smartphones" in this era were hybrid devices that combined these existing familiar PDA OSes with basic phone hardware.

The results were devices that were bulkier than either dedicated mobile phones or PDAs, but allowed a limited amount of cellular Internet access. The trend at the time, however, that manufacturers competed on in both mobile phones and PDAs was to make devices smaller and slimmer.

The bulk of these smartphones combined with their high cost and expensive data plans, plus other drawbacks such as expansion limitations and decreased battery life compared to separate standalone devices, generally limited their popularity to " early adopters " and business users who needed portable connectivity.

The two components were attached by a hinge in what became known as a clamshell design, with the display above and a physical QWERTY keyboard below. The PDA provided e-mail; calendar, address book, calculator and notebook applications; text-based Web browsing; and could send and receive faxes.

When closed, the device could be used as a digital cellular telephone. These phones ran on i-mode, which provided data transmission speeds up to 9. Limited functionality, small screens and limited bandwidth allowed for phones to use the slower data speeds available.

It was also ranked first in market capitalization in Japan and second globally. This power would later wane in the face of the rise of 3G and new phones with advanced wireless network capabilities.

Smartphones were still rare outside Japan until the introduction of the Danger Hiptop in, which saw moderate success among U. Later, in the mids, business users in the U.

American users popularized the term "CrackBerry" in due to the BlackBerry's addictive nature. Initially, Nokia's Symbian smartphones were focused on business with the Eseries, [23] similar to Windows Mobile and BlackBerry devices at the time.

From onwards, Nokia started producing consumer-focused smartphones, popularized by the entertainment-focused Nseries. In Asia, with the exception of Japan, the trend was similar to that of Europe.

In the early to mids, it was common for smartphones to have a physical T9 numeric keypad or QWERTY keyboard in either a candybar or sliding form factor. At that time, many smartphones had resistive touchscreens, which allowed for input with a stylus in addition to fingers, thus allowing the entry of Asian characters.

In, the LG Prada was the first mobile phone released with a large capacitive touchscreen. The iPhone was "not a smartphone by conventional terms, being that a smartphone is a platform device that allows software to be installed," [28] until the opening of Apple's App Store a year later, which became a common means for smartphone software distribution and installation.

Later versions of Android added and then improved on-screen keyboard support, and physical keyboards on Android devices quickly became rare. Although Android's adoption was relatively slow at first, it started to gain widespread popularity in, and in early dominated the smartphone market share worldwide, which continues to this day.

The iPhone and Android phones with their capacitive touchscreens popularized the smartphone form factor based on a large capacitive touchscreen and led to the decline of earlier, keyboard - and keypad-focused platforms.

Microsoft, for instance, discontinued Windows Mobile and started a new touchscreen-oriented OS from scratch, called Windows Phone. Nokia abandoned Symbian and partnered with Microsoft to use Windows Phone on its smartphones.

Windows Phone became the third-most-popular smartphone OS, before being replaced by Windows 10 Mobile, which declined in share to become "largely irrelevant" at less than 0. BlackBerry Limited, formerly known as Research In Motion, made a new platform based on QNX, BlackBerry 10 , with which it was possible to control a device without having to press any physical buttons; this platform was later discontinued.

By the mids, almost all smartphones were touchscreen-only, and Android and iPhone smartphones dominated the market since smartphones started to grow in use by and In, Fairphone launched its first "socially ethical" smartphone at the London Design Festival to address concerns regarding the sourcing of materials in the manufacturing.

In October, Motorola Mobility announced Project Ara, a concept for a modular smartphone platform that would allow users to customize and upgrade their phones with add-on modules that attached magnetically to a frame.

By, p displays began to appear on high-end smartphones. The first mobile phone with a fingerprint scanner was the Toshiba G in and the first smartphone with a fingerprint scanner was the Motorola Atrix 4G in Foldable OLED smartphones have been anticipated for years but have failed to materialize because of the relatively high failure rate when producing these screens.

One of the main characteristics of smartphones is their screen. They are measured in diagonal inches, starting from 2. In the s, Braille screens, which can be used by visually impaired people are being developed.

It is expected that Braille screens will use some type of microfluidics technology. A wide range of accessories are sold for smartphones, including cases, screen protectors, power charging cables, wireless power stations, USB On-The-Go adapters for connecting USB drives and or, in some cases, a HDMI cable to an external monitor, add-on batteries, headphones, combined headphone-microphones which, for example, allow a person to privately conduct calls on the device without holding it to the ear, and Bluetooth - enabled powered speakers that enable users to listen to media from their smartphones wirelessly.

Cases range from relatively inexpensive rubber or soft plastic cases which provide moderate protection from bumps and good protection from scratches to more expensive, heavy-duty cases that combine a rubber padding with a hard outer shell.

Some cases have a "book"-like form, with a cover that the user opens to use the device; when the cover is closed, it protects the screen. Some "book"-like cases have additional pockets for credit cards, thus enabling people to use them as wallets.

Accessories include products sold by the manufacturer of the smartphone and compatible products made by other manufacturers. Smartphone battery life, nowadays, is generally adequate, [58] however, earlier smartphone battery life was poor due to the weak batteries that could not handle the significant power requirements of the smartphones' computer systems and color screens.

External battery packs include generic models which are connected to the smartphone with a cable and custom-made models that "piggyback" onto a smartphone's case. Most recently, Samsung had to recall millions of the Galaxy Note 7 smartphones due to an explosive battery issue.

Android is a mobile operating system founded by Andy Rubin, now owned and developed by Google, and backed by an industry consortium known as the Open Handset Alliance.

Development groups have used the Android source code to develop and distribute their own modified versions of the operating system, such as CyanogenMod now LineageOS, to add features to the OS and provide newer versions of Android to devices that no longer receive official updates from their vendor.

Gartner Research estimated that million Android smartphones were sold during the fourth quarter of, leading all other platforms. Samsung Electronics, who produces Android devices, was also the top smartphone vendor across all platforms in the same period of time.

The iPhone was first unveiled in January The device introduced the use of multi-touch gestures for navigation. However, the iPhone and iOS have generally been in second place in worldwide market share.

Tizen is a Linux-based operating system for devices, including smartphones, tablets, in-vehicle infotainment IVI devices, smart TVs, laptops and smart cameras. This user interface differentiate Jolla smartphones from others.

In, RIM released its first BlackBerry smartphone, providing secure real-time push-email communications on wireless devices. Services such as BlackBerry Messenger provide the integration of all communications into a single inbox.

As of September, there were around 46 million active BlackBerry service subscribers. Throughout its lifespan, the operating system was available in both touchscreen and non-touchscreen formats.

It was supplied with a suite of applications developed with the Microsoft Windows API and was designed to have features and appearance somewhat similar to desktop versions of Windows.

Third parties could develop software for Windows Mobile with no restrictions imposed by Microsoft. Software applications were eventually purchasable from Windows Marketplace for Mobile during the service's brief lifespan.

It was the world's most widely used smartphone operating system until Q4 , though the platform never gained popularity in the U. The first Symbian phone, the touchscreen Ericsson R Smartphone, was released in, [96] [97] and was the first device marketed as a "smartphone".

With the creation of Symbian Foundation in, Symbian OS was unified under one variant under the stewardship of Nokia. In February, Nokia announced that it would replace Symbian with Windows Phone as the operating system on all of its future smartphones, with the platform being abandoned over the following few years.

Firefox OS was demonstrated by Mozilla in February It was designed to have a complete community-based alternative system for mobile devices, using open standards and HTML5 applications.

The Bada operating system for smartphones was announced by Samsung in November On August 18, , HP announced that webOS hardware was to be discontinued [] but would continue to support and update webOS software and develop the webOS ecosystem.

In May, Handspring released the Palm OS Treo smartphone, which did not support Springboard, with both a touchscreen and a full keyboard. The Treo had wireless web browsing, email, calendar, a contact organizer and mobile third-party applications that could be downloaded or synced with a computer.

MeeGo is an operating system created from the source code of Moblin produced by Intel and Maemo produced by Nokia. Before that, Nokia used Maemo on some of its smartphones and internet tablets such as Nokia N and N MeeGo was originally envisioned to power a variety of devices from netbooks, tablets to smartphones and smart TVs.

In, Motorola launched the first smartphone to use Linux, the A handset. Further models to use Linux such as the Motorola Ming Ai in and several successors to the Ming line would be unveiled through In late, Motorola released the Motorola Cliq, [] the first of Motorola's smartphones to run the Linux-based Android operating system.

Subsequently, Motorola stopped developing phones based on other Linux variants. Windows 10 Mobile formerly known as Windows Phone is from Microsoft. It is closed source and proprietary.

It has the third largest installed base on smartphones behind Android and iOS. In January, Microsoft announced that its Windows Phone brand will be phased out and replaced with Windows 10 Mobile, bringing tighter integration and unification with its PC counterpart Windows 10 , and provide a platform for smartphones and tablets with screen sizes under 8 inches.

Windows Mobile smartphone series has had poor adoption, that also led to a decrease in third-party applications, and some vendors ended their support for Windows Mobile altogether.

A mobile app is a computer program designed to run on a mobile device such as a smartphone or tablet. The term "app" is a shortening of the term "software application".

The introduction of Apple's App Store for the iPhone and iPod Touch in July popularized manufacturer-hosted online distribution for third-party applications software and computer programs focused on a single platform.

There are a huge variety of apps, including video games, music products and business tools. Up until that point, smartphone application distribution depended on third-party sources providing applications for multiple platforms, such as GetJar, Handango, Handmark, and PocketGear.

Since, smartphone shipments have had positive growth. The situation was caused by the maturing China market. In, Samsung had the highest shipment market share worldwide, followed by Apple.

In, Samsung had Only Apple lost market share, although their shipment volume still increased by Samsung's mobile business is half the size of Apple's, by revenue. Apple business has been increasing very rapidly over the past 4 years.

The market has been dominated by the Android operating system since Android's market share measured by units shipment rose from Windows Phone market share also oscillated between 1. As of the end of Q4 , Android was the most popular operating system sold with new smartphones with an A University of Southern California study found that unprotected adolescent sexual activity was more common among owners of smartphones.

Mobile phone use while driving—including talking on the phone, texting, playing media, web browsing, gaming, using mapping apps or operating other phone features—is common but controversial, since it is widely considered dangerous due to what's known as distracted driving.

Being distracted while operating a motor vehicle has been shown to increase the risk of accidents. In Egypt, Israel, Japan, Portugal and Singapore, both handheld and hands-free calling on a mobile phone which uses a speakerphone is banned.

In other countries including the UK and France and in many US states, only the use of calling on handheld phones is banned, while hands-free use is permitted. A simulation study at the University of Utah found a sixfold increase in distraction-related accidents when texting.

This is more apparent in countries which ban both handheld and hands-free usage, rather than those which ban handheld use only, as officials cannot easily tell which function of the phone is being used simply by looking at the driver.

This can lead to drivers being stopped for using their device illegally for a call when, in fact, they were using the device legally, for example, when using the phone's incorporated controls for car stereo, GPS or satnav.

A study reviewed the incidence of phone use while cycling and its effects on behavior and safety. Accidents involving a driver being distracted by being in a call on a phone have begun to be prosecuted as negligence similar to speeding.

New Zealand has banned handheld phone use since 1 November Many states in the United States have banned text messaging on phones while driving. Illinois became the 17th American state to enforce this law.

This database of laws provides a comprehensive view of the provisions of laws that restrict the use of mobile devices while driving for all 50 states and the District of Columbia between, when first law was passed through December 1, The dataset contains information on 22 dichotomous, continuous or categorical variables including, for example, activities regulated e.

There was also smartphone patents licensing and litigation involving Sony Mobile, Google, Apple Inc. The conflict is part of the wider "patent wars" between multinational technology and software corporations.

To secure and increase market share, companies granted a patent can sue to prevent competitors from using the methods the patent covers. Since the 's the number of lawsuits, counter-suits, and trade complaints based on patents and designs in the market for smartphones, and devices based on smartphone OSes such as Android and iOS, has increased significantly.

Initial suits, countersuits, rulings, license agreements, and other major events began in as the smartphone market stated to grow more rapidly by With the rise in number of mobile medical apps in the market place, government regulatory agencies raised concerns on the safety of the use of such applications.

These concerns were transformed into regulation initiatives worldwide with the aim of safeguarding users from untrusted medical advice. Smartphone malware is easily distributed through an insecure app store.

An online petition has urged smartphone makers to install kill switches in their devices. Leaked documents published by WikiLeaks, codenamed Vault 7 and dated from —, detail the capabilities of the United States Central Intelligence Agency CIA to perform electronic surveillance and cyber warfare, including the ability to compromise the operating systems of most smartphones including iOS and Android.

Using smartphones late at night can disturb sleep, due to the brightly lit screen affecting melatonin levels and sleep cycles. In an effort to alleviate these issues, several apps that change the color temperature of a screen to a warmer hue based on the time of day to reduce the amount of blue light generated have been developed for Android, while iOS 9.

Amazon released a feature known as "blue shade" in their Fire OS "Bellini" 5. It has also been theorized that for some users, addicted use of their phones, especially before they go to bed, can result in " ego depletion ".

Many people also use their phones as alarm clocks, which can also lead to loss of sleep. Pocket camera has difficulty to produce bokeh image, but nowadays some smartphone has dual-lens camera to produce bokeh easily, and even the level of bokeh can be arranged after shoot.

They are the Best Performing LCD displays that we have ever tested, but the iPhone 6 has been downgraded because it only has a 1.

Many Smartphones still have greater than 10 percent reflections that make the. Hopefully manufacturers will reduce the mirror reflections with anti-reflection coatings and. All of the iPhones have approximately same Reflectance because they are all very close to the minimum possible with.

Light From All Directions. Measured using an Integrating Hemisphere and. The best value we have. Percentage of Light Reflected. These are the most annoying types of Reflections.

Measured using a Spectroradiometer and a narrow. The Contrast Ratio is the specification that gets the most attention, but it only applies for low ambient light, which is seldom.

Much more important is the Contrast Rating, which indicates how easy it is to read the screen. The larger the better. This is due in part to the automated factory calibration performed on each individual display at the factory.

This is the Brightness for typical screen content. This is the Brightness for a screen that is entirely. This is the Peak Brightness for a screen that. Some displays including the iPhone 6 have.

Brightness Slider to Minimum. For Very Low Light. This is the Lowest Brightness with the Slider set to. This is useful for working in very dark. Picture Quality remained Excellent. True Black Brightness at 0 lux.

Very Good for Mobile. Black brightness is important for low ambient light,. True Contrast Ratio at 0 lux. Relevant for Low Ambient Light. Only relevant for Low Ambient Light,. The Higher the Better.

Depends on the Screen Reflectance and Brightness. Some displays have higher Brightness. Indicates how easy it is to read the screen. Bigger is definitely Not Better because the display needs to match all the standards that were used.

The iPhone 6 and 6 Plus are much better calibrated with significantly improved Absolute Color Accuracy and. The iPhone 6 and 6 Plus continue with a Slightly Bluish. White Point, but somewhat less than the iPhone 5.

The White Point Accuracy is more critical than for other colors. Color Temperature in degrees. Measured in the dark at 0 lux. For the Plotted White Points. White is Somewhat Bluish.

White is Slightly Bluish. D65 with 6, K is the standard color of White. White Point Accuracy is more critical than other Colors. Fairly Close to Standard. Very Close to Standard. Average Color Error at 0 lux.

For 21 Reference Colors. J ust N oticeable C olor D ifference. Accuracy Plots showing the measured Color Errors. Average Errors below 3. Average Errors above 7. Largest Color Error at 0 lux. Largest Errors above This is twice the limit for the Average Error.

This is the percent Brightness decrease with APL. Ideally should be 0 percent. Very Smooth and Straight. The Intensity Scale controls image contrast needed. Gamma for the Intensity Scale. Larger has more Image Contrast.

Gamma Slightly Too High. Gamma is the log slope of the Intensity Scale. For most LCDs there are substantial. Note that the Viewing Angle performance is also very important for a single viewer because the Viewing Angle can vary.

The Viewing Angle can be very large if resting on a table or desk. The iPhone 6 and 6 Plus have significantly better Viewing Angle performance than the iPhone 5 or any other. LCD that we have ever tested.

Particularly important and noticeable are the much higher Contrast Ratios and. Most screens become less bright when tilted. LCD decrease is due to optical absorption. LCD decrease is generally greater than 50 percent.

Contrast Ratio at 0 lux. A measure of screen readability when the screen. White Point Color Shift. Color Shifts for Color Mixtures. Reference Brown, , 0. Reference Brown is a good indicator of color shifts.

Since the displays all have different screen sizes and maximum brightness, the values were also scaled to the. The results are all scaled for the same brightness Luminance and same screen area.

Comparison with the iPhone 5. LCDs are typically more power efficient for images with mostly white content like text screens, for example, while OLEDs.

Average Picture Level average Brightness of the image content. For mixed image content that includes photos, videos, and movies, for example with a typical 50 percent Average Picture Level,.

Smartphones are typically pocket-sized, as opposed to tablets, which are much larger. Most basic apps e. Apps can receive bug fixes and gain additional functionality through software updates ; similarly, operating systems are able to update.

Modern smartphones have a touchscreen color display with a graphical user interface that covers the front surface and enables the user to use a virtual keyboard to type and press onscreen icons to activate " app " features.

The original and historic working models are still in the possession of Paraskevakos. These operating systems would later evolve into early mobile operating systems.

Most of the "smartphones" in this era were hybrid devices that combined these existing familiar PDA OSes with basic phone hardware. The results were devices that were bulkier than either dedicated mobile phones or PDAs, but allowed a limited amount of cellular Internet access.

The trend at the time, however, that manufacturers competed on in both mobile phones and PDAs was to make devices smaller and slimmer. The bulk of these smartphones combined with their high cost and expensive data plans, plus other drawbacks such as expansion limitations and decreased battery life compared to separate standalone devices, generally limited their popularity to " early adopters " and business users who needed portable connectivity.

It was also ranked first in market capitalization in Japan and second globally. This power would later wane in the face of the rise of 3G and new phones with advanced wireless network capabilities.

Smartphones were still rare outside Japan until the introduction of the Danger Hiptop in, which saw moderate success among U. Later, in the mids, business users in the U. American users popularized the term "CrackBerry" in due to the BlackBerry's addictive nature.

Initially, Nokia's Symbian smartphones were focused on business with the Eseries, [23] similar to Windows Mobile and BlackBerry devices at the time. From onwards, Nokia started producing consumer-focused smartphones, popularized by the entertainment-focused Nseries.

In Asia, with the exception of Japan, the trend was similar to that of Europe. In the early to mids, it was common for smartphones to have a physical T9 numeric keypad or QWERTY keyboard in either a candybar or sliding form factor.

At that time, many smartphones had resistive touchscreens, which allowed for input with a stylus in addition to fingers, thus allowing the entry of Asian characters.

Windows Phone became the third-most-popular smartphone OS, before being replaced by Windows 10 Mobile, which declined in share to become "largely irrelevant" at less than 0.

BlackBerry Limited, formerly known as Research In Motion, made a new platform based on QNX, BlackBerry 10 , with which it was possible to control a device without having to press any physical buttons; this platform was later discontinued.

Android is a mobile operating system founded by Andy Rubin, now owned and developed by Google, and backed by an industry consortium known as the Open Handset Alliance. Development groups have used the Android source code to develop and distribute their own modified versions of the operating system, such as CyanogenMod now LineageOS, to add features to the OS and provide newer versions of Android to devices that no longer receive official updates from their vendor.

As of September, there were around 46 million active BlackBerry service subscribers. Throughout its lifespan, the operating system was available in both touchscreen and non-touchscreen formats.

It was supplied with a suite of applications developed with the Microsoft Windows API and was designed to have features and appearance somewhat similar to desktop versions of Windows.

Firefox OS was demonstrated by Mozilla in February It was designed to have a complete community-based alternative system for mobile devices, using open standards and HTML5 applications.

Subsequently, Motorola stopped developing phones based on other Linux variants. Windows 10 Mobile formerly known as Windows Phone is from Microsoft. It is closed source and proprietary.

Windows Mobile smartphone series has had poor adoption, that also led to a decrease in third-party applications, and some vendors ended their support for Windows Mobile altogether. A mobile app is a computer program designed to run on a mobile device such as a smartphone or tablet.

The term "app" is a shortening of the term "software application". The introduction of Apple's App Store for the iPhone and iPod Touch in July popularized manufacturer-hosted online distribution for third-party applications software and computer programs focused on a single platform.

Since, smartphone shipments have had positive growth. The situation was caused by the maturing China market. In, Samsung had the highest shipment market share worldwide, followed by Apple.

The market has been dominated by the Android operating system since Android's market share measured by units shipment rose from Windows Phone market share also oscillated between 1.

As of the end of Q4 , Android was the most popular operating system sold with new smartphones with an A University of Southern California study found that unprotected adolescent sexual activity was more common among owners of smartphones.
